Im looking to add a delay to the end of a track (for echo effect), but when I click on the "Audio Effects" tab, nothing happens. I don't get a list of effects, but believe Ableton is supposed to have some by default.

I'm using a licensed version, I haven't used Ableton in some time - but when I had used it for a project effects years ago, it used to show but now nothing happens when I click on any of the plugins, effects etc. Nothing appears in search either. Are you saving effects in .adg format as well?
